Comment 5 for bug 611474

We have the same issue on the Dell Precision T7500. Interestingly, it used to work with an earlier kernel, as we have been running this machine on Lucid without flaws for months. After a planned outage, we started getting "Gave up waiting for root device" on boot, and a prompt to busybox. The bootdelay=60 doesn't work for us either.

The main issue that I am seeing is that the disk comes up, but the /dev/disk/by-uuid directory is missing. Since Grub is looking for root via UUID, the boot fails. If I change root to "root=/dev/sda1" it comes up, but hangs later because it still wants to mount all the partitions by UUID and the directory is still gone. Again, this is a new issue from one of the later kernels.
